ABOUT
Our mission at impulse tubing is to supply our customers with the highest quality formed tubes and tubing assemblies at an unparalleled value. Established by a new-space engineer, Impulse Tubing understands the needs of high-end aerospace applications such as welded or brazed tubing assemblies. However, we also recognize the need to provide quick-turn, low-cost solutions as well. While we make use of a number of partner organizations to ensure your prototyping and production needs are met in a timely fashion, we are constantly growing our internal production capacity to vertically integrate; providing you the best value for your business.

CAPABILITIES
DESIGN FOR MANUFACTURE
Assure lower-cost, production worthy parts by adhering to a few simple guidelines.
01
02
03
Use Commonly Available Tube Sizes and Materials
Stick With Common Bend Radii
Avoid Knots, 180 Degree Bends and Long Straights Between Bends
The size and material selection of your formed tube may have a significant impact on lead time and cost of production. Common alloys such as 300 series stainless steels or copper alloys have good availability. In addition, the use of common imperial/metric diameters and wall thicknesses or using common pipe sizes and schedules will improve the availability of the material stock and associated tooling.
04
Make Use of Standard Tolerances
If possible, use a centerline radius that is 2x or 3x that of the tube diameter (these are the most common centerline radiii). Tighter or looser radii can be formed; however, this may require custom tooling for your job. In addition to proper bend radii selection, avoid using different bend radii within any tubing run. The use of multiple radii will negatively impact lead time and cost.
05
Leave Room Between Bends and at Ends
Even when using standard tube sizes and bend radii, there are certain configurations that will be problematic. Examples include "knots", bends close to and above 180 degrees, tight coils with stiff material, and long bend lengths in some cases.
06
Keep the Bend Factor Low
The standard tolerance for Impulse's tubing assemblies is .030" end-to-end and .060 along the tube profile. Long runs of tubing will be inspected in the restrained condition. Use tube flexibility to your advantage where you can. Reduced tolerance requirements results in a lower-cost part.
Maintain a distance between bend tangents that is 3X that of the tube diameter. This allows sufficient space for the tube bender pressure and clamping dies. For flared ends, allow enough length for the clamping die of the flare tooling. This should be at least 1" from the sleeve when aligned with the tangency of the closest bend. For tube sizes larger than 1/2", the minimum distance should be 3x that of the tubing diameter.
A good rule of thumb is to keep the bend factor less than 1 for any given bend along a tube. Bend factors greater than 1 are achievable, but are generally more difficult to produce and may require special tooling. The bend factor can be computed from the equation below:
